ok, I am looking at the examples right now, and I've got a question:
what is the 'peer' IP address - is it the IP assigned 
from /etc/ppp/chap-secrets or is it the real IP address of the client?

so according to my needs, it should be:
 peer (my clients get assigned those IPs)
 peer (any client can be the peer end, meaning a road warrior)

I don't want to use any inner-pppd, so as I can see I have no other option, 
but rp-l2tp to support road warriors with 'always-the-same-IPs' assigned, 

thank you very much!
